[Cialug] Firewall question

[Sean Flattery]

Which system is your DHCP server, and what default route is it telling to
DHCP clients?  Make sure you don't have both your firewall and wireless
router handing out DHCP.

I will try to get more detailed later (busy today) but the traceroute
command comes back with two lines.  both reference the base IP of the
router which is 192.168.9.1.  I agree that the problem is with not being
able to get to the internal firewall side which is 192.168.9.254 fixed IP.
If I am logged into the firewall machine I can ping by IP or name.

ie: ping 8.8.8.8 with a valid response  (also)
     ping www.google.com resolves and .properly as well.

I can ssh to the firewall at 192.168.9.254 without any issue and perform
the above commands without issue.

>*From the local machine terminal window both commands fail.

Right now the wireless access point does not have an internet connection.
Just trying to route through the firewall to the existing network which
works fine.  When I tried to connect this wireless device to my cable modem
directly I crashed the whole network.  Firewall did not work.
